A Case Report of a Huge Mesenteric Cyst in a 5-Year-Old Girl: A Rare and Challenging Finding in Radiological Assessment

Introduction: Mesenteric cysts are rare benign intra-abdominal vesicles with various clinical presentations. They almost located in the mesentery of the small intestine. The selective therapeutic method is complete surgical excision, however more than half need resection and bowel anastomosis. Case presentation: Here, we presented a 5-year-old girl with a huge mesenteric cyst (15×14cm2) mesenteric cyst that was excised surgically., which the diagnosis confirmed by computed tomography scan and managed through surgical excision. Conclusion: Acute abdominal pain may be due to the presence of mesenteric cysts, but it is not always possible to differentiate and diagnose it preoperatively, and this challenge especially exists in the case of bulky masses. it is recommended to choose primary radical, surgical treatment in case of intra-abdominal cystic mass in the pediatric age

Prevalence of Microalbuminuria in Children with Asymptomatic Microscopic Hematuria

Introduction: A wide range of chronic and acute diseases begin with asymptomatic microscopic hematuria. Simultaneous presence of microalbuminuria and microscopic hematuria is suggestive of an important kidney disease. The purpose of this study was to determine the prevalence of microalbuminuria in children with asymptomatic microscopic hematuria.Materials and Methods: This cross-sectional study was done on 150 children aged 2-14 years with asymptomatic microscopic hematuria at Nephrology Clinic of Children’s Hospital Medical Center in 2013-2015. All patients had clinical and laboratory tests such as BUN, creatinine, electrolytes, urine albumin/ creatinine ratio, blood pressure, etc. The obtained data were recorded and analyzed with SPSS (ver. 18). All children with anatomical anomalies, hypertension, previous urinary tract surgery, or nephrolithiasis were excluded from the study.Results: The overall prevalence of microalbuminuria was 14.5 % and there was a significant relationship between microalbuminuria and the presence of dysmorphic red blood cells on urine analysis (p-value<0.05). The incidence of RBC cast was 54% (82 patients). Two children had upper-normal levels of blood pressure for age and sex that were followed closely and received special diets and medications. Twenty-nine patients (18.6%) had a positive family history of asymptomatic microscopic hematuria and the father of one of them had IgA nephropathy with ESRD. In children with microalbuminuria that received drugs for 3-28 months (mean, 6.3 months), microalbuminuria decreased significantly.Conclusions: Isolated asymptomatic microscopic hematuria is a benign disease but its association with proteinuria may indicate a serious problem with the risk of progressive renal disease. It is recommended to determine the microalbumin/creatinine ratio in cases with asymptomatic microscopic hematuria. Keywords: Asymptomatic Microscopic Hematuria; Microalbuminuria; Prevalence; Child

Modified magnetite nanoparticles with cetyltrimethylammonium bromide as superior adsorbent for rapid removal of the disperse dyes from wastewater of textile companies

This paper reports application of cetyltrimethylammonium bromide (CTAB) coated magnetite nanoparticles (Fe3O4 NPs) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was investigated and optimized. The obtained results showed that the ratio of initial dye concentration to CTAB amounts has critical effect on removal processes so that removal efficiencies higher than 95% can be achieved even at high concentration of dyes as high as 500 mg l-1 when the ratio is optimum. Removal of dyes is very fast, and equilibrium is reached at times less than 10 min even for high concentration of the dyes. Very high adsorbent capacity (as high as 2000 mg g-1) was yielded for maximum tested concentration of the dyes (500 mg g-1). The obtained result was confirmed by thermogravimetric analysis data. This study showed that CTAB coated Fe3O4 NPs is a very efficient adsorbent for removal of dyes from wastewater of textile companies and has high capacity under optimum conditions

Gastric Perforation, a Rare Consequence of Unintentional Esophageal Intubation

Accidental esophageal intubation is a preventable human error that complicates airway management and continues to occur despite advances in medical devices. Perforation of the stomach has been associated with esophageal intubation in several case reports.This report presents a case of an elderly woman suspected of having COVID-19-related pneumonia. She was intubated due to respiratory dysfunction. In the initial few minutes, the patient became desaturated, leading to a second intubation. An hour later, the patient’s abdomen was distended, and the chest computed tomography (CT) showed a massive pneumoperitoneum. During laparotomy, a 6 cm long rupture was found in the lesser curvature, which was attributed to accidental esophageal intubation. To avoid such a fatal condition, it is imperative for physicians to ensure the correct positioning of the endotracheal tube. To achieve this goal, further investigation into readily available and highl y sensitive techniques is recommended

Alendronate improves fasting plasma glucose and insulin sensitivity and decreases insulin resistance in prediabetic osteopenic postmenopausal women: a randomized triple-blind clinical trial

Aims Postmenopausal women receive bisphosphonates for osteoporosis treatment. The effect of these medications on developing diabetes mellitus (DM) in prediabetic patients is yet to be investigated. We aimed to determine the effect of alendronate on plasma glucose, insulin indices of postmenopausal women with prediabetes and osteopenia. Methods This triple‐blind randomized controlled clinical trial included 60 postmenopausal women, aged 45–60 years. All patients were vitamin D sufficient. They were randomly enrolled in intervention (70 mg/week alendronate for 12 week) and control (placebo tablet per week for 12 weeks) groups. The morning 8 hour fasting blood samples were collected at the baseline and follow–up visits to measure the fasting plasma glucose (FPG) (mg/dl), insulin and hemoglobin A1c (HbA1c). Plasma glucose and insulin concentration were measured 30, 60, and 120 minutes after glucose tolerance test. Matsuda index, homeostasis model assessment of insulin resistance (HOMA–IR), homeostasis model assessment of beta–cell function (HOMA–B) and the area under the curves (AUC) of glucose and insulin were calculated. Results Mean (SD) FPG (102.43 (1.46) mg/dl vs. 94.23)1.17) mg/dl, P=0.001), 120‐minutes insulin concentration (101.86)15.70) mU/l vs. 72.60 (11.36), P=0.026), HbA1c (5.60 (0.06) % vs. 5.40 (0.05)%, P=0.001), HOMA‐IR (3.57 (0.45) vs. 2.62 (0.24), P=0.021) and Matsuda index (7.7 (0.41) vs. 9.2 (0.4), P=0.001) significantly improved in the alendronate‐treated group. There was statistically significant more reductions in FPG (‐8.2 (8.63) mg/dl vs. ‐2.5 (14.26) mg/dl, P=0.002) and HbA1c (‐0.2 (0.23) % vs. ‐0.09 (0.26) %, P=0.015) were observed in alendronate‐treated group than placebo group during the study course, respectively. Conclusions Administration of 70 mg/week alendronate improves fasting plasma glucose, HbA1c and insulin indices in postmenopausal women

Mantle-flow diversion beneath the Iranian plateau induced by Zagros' lithospheric keel.

Funder: German Research Foundation (DFG)Funder: Projekt DEALPrevious investigation of seismic anisotropy indicates the presence of a simple mantle flow regime beneath the Turkish-Anatolian Plateau and Arabian Plate. Numerical modeling suggests that this simple flow is a component of a large-scale global mantle flow associated with the African superplume, which plays a key role in the geodynamic framework of the Arabia-Eurasia continental collision zone. However, the extent and impact of the flow pattern farther east beneath the Iranian Plateau and Zagros remains unclear. While the relatively smoothly varying lithospheric thickness beneath the Anatolian Plateau and Arabian Plate allows progress of the simple mantle flow, the variable lithospheric thickness across the Iranian Plateau is expected to impose additional boundary conditions on the mantle flow field. In this study, for the first time, we use an unprecedented data set of seismic waveforms from a network of 245 seismic stations to examine the mantle flow pattern and lithospheric deformation over the entire region of the Iranian Plateau and Zagros by investigation of seismic anisotropy. We also examine the correlation between the pattern of seismic anisotropy, plate motion using GPS velocities and surface strain fields. Our study reveals a complex pattern of seismic anisotropy that implies a similarly complex mantle flow field. The pattern of seismic anisotropy suggests that the regional simple mantle flow beneath the Arabian Platform and eastern Turkey deflects as a circular flow around the thick Zagros lithosphere. This circular flow merges into a toroidal component beneath the NW Zagros that is likely an indicator of a lateral discontinuity in the lithosphere. Our examination also suggests that the main lithospheric deformation in the Zagros occurs as an axial shortening across the belt, whereas in the eastern Alborz and Kopeh-Dagh a belt-parallel horizontal lithospheric deformation plays a major role

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories. The high quality of the papers and the discussion represent the thinking and experience of experts in their particular fields. The contributed papers also relate to the methodology used in libraries in Asia to provide access to manuscripts and cultural heritage. The volume discusses best practices in Knowledge preservation and how to collaborate and preserve the culture. The book also deals with manuscript and archives issues in the digital era. The approach of this book is concise, comprehensively, covering all major aspects of preservation and conservation through libraries. The readership of the book is not just limited to library and information science professionals, but also for those involved in conservation, preservation, restoration or other related disciplines. The book will be useful for librarians, archivists and conservators. We thank the Sunan Kalijaga University, Special Libraries Association- Asian Chapter for their trust and their constant support, all the contributors for their submissions, the members of the Local and International Committee for their reviewing effort for making this publication possible

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Determination of biphenyl and biphenyl oxide in aqueous samples by headspace single drop microextraction coupled to gas chromatography

In this work, biphenyl and biphenyl oxide were extracted by headspace single drop microextraction (HS-SDME) and analyzed by gas chromatography-flame ionization detection (GC-FID). The extraction occurred from the tip of a microsyringe by suspending a 3.5 µL drop of toluene, as extracting solvent, containing acetonaphton, as internal standard. The effect of different parameters such as the nature of extraction solvent, microdrop and sample temperatures, stirring rate, microdrop and sample volumes, ionic strength and extracting time on the extraction efficiency of the analytes were investigated and optimized. Under optimized conditions the limits of detection (S/N = 3) of biphenyl and biphenyl oxide were 0.40 ± 0.03 and 0.30 ± 0.06 µg mL‑1, respectively. Good linearities were obtained for both analytes with the correlation coefficients higher than 0.997 and the relative standard deviations (R.S.D.) were in the range of 1-3%. The recoveries of analytes from spiked water samples were near to 100%
